What is the 7 7 rule for winter tires?
If you leave them on too late, your winter tires will degrade quickly. So, when is the right time to swap? The rule of thumb is 7-for-7: wait until there are seven consistent days at 7 degrees Celsius. Compared with a standard all-season tire, a winter tire has a softer rubber compound, and because of that, it generally wears out quicker in terms of mileage — lasting about 40,000 miles as opposed to around 60,000 for an all-season.Once the thermometer consistently reads 7°C or below, all-season tires begin to harden and lose effectiveness, whereas winter tires stay soft and grippy. This difference means better braking, cornering, and acceleration on winter roads, which can be critical for avoiding accidents.Based on the weather: It’s time to install your winter tires when nighttime and early morning temperatures stay at or near 40º F. Yes, it’s okay if daytime temperatures hover in the upper 50s. You won’t ruin your winter tires overnight, but they will wear out faster as temperatures rise.Rough on roads – The deep tread grip of winter tires can dig into the asphalt on the road, so you should only use them during the winter. If you drive with snow tires year-round, you can damage your tires and the road, causing potholes and cracks in the asphalt.Early Winter Preparation: For those anticipating early winter weather, fall is an ideal time to switch to winter tires before the first snowfall. Buying winter tires in the fall ensures you are well-prepared and can avoid the rush when demand is high.

The average price range of a set of performance winter tires is between $800 and $2,000.Install winter tires before freezing temperatures hit.

What is the best time to buy snow tires?
Buy Them At the Right Time You have to hurry because tire rebates and offers have an expiration date. That date typically lands for snow tires in October, November, or December. Winter tires don’t like warm conditions It’s the rubber compound, which is formulated to stay soft and pliable when temperatures plummet below 7 °C (46 °F). It’s very effective for mitigating the negative impact of cold temperatures and provides traction in winter conditions.Tire pricing can fluctuate throughout the year, with significant discounts often available during certain times. Early fall and late spring tend to be good times to purchase new tires, as many retailers discount old stock to make room for new models.This rubber, however, degenerates much more quickly when the temperature rises. If you decide to keep your winter tires on all year, the tread-wear indicators showing it’s time to buy new tires will appear more quickly, generally after less than 10,000 kilometres.
